Description:

Generates a layout file with some handy utilities:

 - Bootstrap (or a Bootswatch)
 - Font Awesome
 - A navbar with
    - links to all detected index pages
    - links to all detected registration and sign in forms
 - Components to display flash notices and alerts
 - A sticky footer

Specify "none" as the THEME_NAME to use vanilla Bootstrap; or, choose a
Bootswatch. As of this writing, available Bootswatches are:

  - cerulean
  - cosmo
  - cyborg
  - darkly
  - flatly
  - journal
  - lumen
  - none
  - paper
  - readable
  - sandstone
  - simplex
  - slate
  - spacelab
  - superhero
  - united
  - yeti

WARNING: You will lose any modifications you've made to your current layout
if you choose to overwrite it. You can also specify a different filename
other than "application" with the --layout-file option.

Examples:

    rails generate draft:layout

    rails generate draft:layout --theme=paper

    rails generate draft:layout --layout-file=some_other_filename

    rails generate draft:layout --skip-cdn

(The last one omits links to CDN-hosted Bootstrap CSS, JS, and Font Awesome,
in case you are e.g. bundling them yourself using gems.)
